To alt whom it i Be known that Liltossnti. Tor e'nn, a citizen of the United States, andfa; resident of Cochituate, in the "countyiof 'MiddleseX and Commonwealth of Massachusetts, have {invented certain ne an useful Imrovements in GurtainLights, of which the ollowing is cation. e Y

Theobject ofg'this inventionisjthe 'con. struction of improvedmeans'ffor'; renewing in'ur-ed and broken lights inf'ai toihobile our teams and thellike, whereby [the'frefpairing can be done by theowner grcliaujeurpof the car without sendingthe curtain away to an expert;

vice which can be clamped about the edges of a light and attached to the curtain by projecting spurs.

In the drawings forming part of this specification, Figure 1 is an elevation of a portion of a curtain showing a light attached thereto by my improved means. Fig. 2 is an elevation of parts of the same viewed from within the car. Fig. 3 is a face view of a section of the sheet metal device before it has been doubled on itself laterally. Fig. 4 is a View of the same after being doubled. Fig. 5 is a. perspective view of the same. Fig. 6 is a section. Fig. 7 is a cross section on the line 77 in Fig. 5.

Referring to Fig. 2, the reference numeral 1 designates a portion of a curtain having an opening into which a new light 2 of celluloid or the like has been fitted; 3 is the attaching device, and 4 is the binding which is ordinarily stitched to the curtain and original light about the illuminating open- WVhen the attaching device is made as a long strip, it has its edges given numerous V-shaped notches 5, as shown most clearly in Fig. 3, to enable it to be easily bent to fit a rounded outline, as shown in Fig. 1. In one edge, slits 6 are cut approximately to the bend 7 and the tongues 9 thus formed are sharpened to render easier their penetration in the fabric composing the binding 4. When this metal strip is ready for use, its fingers or spurs 9 are standing at right angles to its surface, as shown in Figs. 5 and 7.

Further, indentations 10 are impressed in the device, as shown in Fig. 3, in order to insure againstfwithdrawal of the light.

In using this means of attachment, the

stitches near' the edge of the binding 4 by which the damaged light was originally held in place, are carefully cut in order to separate this edge of the bindi11g from the light and the curtain. The old light being removed and the new sheet oftransparent 'n'1ateria'l having been put to compose the I light'2, the attaching means 3 is pressed 3 fever-1 itsedges and made to securely'hold To this end, I provide a sheet metal deblow or two over the indentations 10 to force the projections 11 into the celluloicl. Then the metal-inclosed edges of the light 2 are introduced between the binding 4 and the curtain l, and the spurs 9 are forced through the binding and bent flat against the surface of the binding, as shown in Figs. 2 and 6.

All that now remains is to cement the inner edges of the binding and curtain to the contacting surfaces of the light, and the task is complete.

When a light thus inserted becomes injured, it is an easy thing to run a knife edge between the cemented surfaces; then to unbend the spurs 9; remove the light and its attaching strip; pry the two leaves of the latter apart to remove the damaged light, and to introduce and cement a fresh light in the manner already described.

Although I have shown the attaching device as a single long strip of sheet metal, it is evident that more than one length can be used on a light, the only thing essential being that at least one of the spurs 9 and one or two of the projections 11 shall be provided for each length or section.

It is readily seen that this device furnishes not only a convenient and neat means for replacing old lights with new, but it can be applied in the attachment of lights to curtains when originally manufactured.

What I claim is:

1. A clamping device for sheet material, comprising a section of sheet metal folded over upon itself to compose two spaced members, one of said members having a projection on its inner surface, and one member having a spur projecting therefrom vvhereby sheet matbrial can clamped between said members and other sheet material can be held by said spur.

2. The combination with a fabric having an opening through it and a sheet to be at tached over the opening, of an attaching device comprising a section of sheet metal folded over upon itself to compose tvvo spaced'members, one memberhaving pro 'ections on its inner surface, and a member avmg, a pomted spur pro ect1ng therei from, said members having an edge of said sheet held betvveen themjby said projections,

and said spur being 'thrust throughand bent down upon sai fabric. v.

3. Aclamping strip composed of sheet metal folded over upon itself along a longitudinal' line to form two" spaced members having inward projections vandoutwardly projecting spurs; whereby sheet material can be-clamped bet'vveensaid members, and

other sheet material can be held by said spurs. I v

4; The combinationwlth a fabric having an opening through it and a sheet to be at taehed over the opening, of a, binding strip stitched to the fabric near its edge spaced spond with the opening.

from the edgeof 'the opeiiing, a a clamping' strip composed of sheet metal folded over upon. itself; along ayiongitudinal line and inclosing the edges of the said sheet,

the clamping strip having pointed projections for engaging said sheet and pointed spurs for engaging said binding, said strip being disposed between the binding and fabrlc and cemented'therfiinf 5.
